CHANGEABLE WINDOW SASH Filed Jan. 28, 1935 I if.

ATTOR N EYS Patented June 30, 1936 UNITED STATES PATENT OFFIQE 1 Claim.

The invention relates to a window sash construction and more especially to a changeable Window sash.

The object of the invention is the provision of a sash of this character, wherein the same is changeable to function as an upper sash or a lower sash and the weight cords being readily fastened thereto for the balancing of the sash when in place within a window frame, the side rails of the sash being constructed so that the weight cords can be housed in channels therein to avoid interference in the working thereof.

A further object of the invention is the provision of a sash of this character, which is simple in its construction, reliable and efficient for changing of the same to function as an upper sash or a lower sash, strong, durable, neat in appearance, and inexpensive to manufacture and install.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described in detail, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention, and pointed out in the claim hereunto appended.

In the accompanying drawing:

Figure 1 is a perspective view partly broken away of the sash constructed in accordance with the invention, showing the meeting rail thereof separated for the removability of the glass pane or panel.

Figure 2 is a view similar to Figure 1 showing the meeting rail made fast and the panel or pane within the sash.

Figure 3 is a vertical longitudinal sectional view showing the sash functioning both as an upper and lower sash.

Figure 4 is a fragmentary vertical sectional view taken at the fastening points of the meeting rails of the upper and lower sashes.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, A designates generally a window sash constructed in accordance with the invention and comprising the side rails or pieces l0, meeting rail II and the opposite end rail l2, respectively. The meeting rail l l at opposite ends thereof is formed with the incuts I3 and M to provide the mortise tong'ues l5 and. overlaps [6, respectively, while the side rails ID at their ends next to the meeting rail are provided with recesses I! for accommodating the mortise tongues l5 of said meeting rail II while the overlaps 86 will lie crosswise of the side rails IE2 at the faces 18 thereof. This meeting rail I l is detachably secured or mortised with the side rails I53 through screw fasteners l9, these being worked home through the overlaps l6, side rails H3 and mortise tongues I5.

The side rails l9, meeting rail II and end rail !2 at their inner edges are provided with channels 20 constituting a seat for the glass pane or panel 2! which is held firm and secure but removable by the meeting rail II.

The end rail !2 has the mortise connection 22 with the side rails H] but is permanently joined therewith.

Each outer edge of the side rails ID has formed therein a rope channel 23 which extends close to the recesses I l longitudinally of said rails to a point close to the mortise connection 22 there being an interrupting web 24 provided therein separating the recess I? in the side rail In from the said channel and this web 24 is adapted to be cut away when the sash is serving as an upper or lower sash in a window frame to give an open course in the channel 23 for a weight cord (not shown), the tongue I5 and the outermost end of said rail also being channeled for this purpose Intersecting the channel 23 intermediate thereof is a knot socket 225 for a knot as formed in the weight cord for the convenient fastening of such cord to the sash, as is conventional.

The meeting rail l I has the beveled side 26, as is usual, for the closing of the gap between the upper and lower sashes in a window frame.

It is, of course, understood that when the sash is used as a lower sash the end rail is lowermost and when such sash is used as an upper sash the said end rail is uppermost, this placing the meeting rail H at the center of the window frame or approximately so, the sash being reversed for these positions, as should be obvious.

What is claimed is:

A changeable window sash as described, comprising an end rail, side rails, and a removable meeting rail interfitting the side rails, and said side rails having longitudinally extending weight cord channels which terminate in breakable webs which are located adjacent to the points of connection of the meeting and end rails with the said side rails and which side rails have knot sockets therein at the center of the channeled edges of said side rails.
